Abstract

A method of handing over in a communication system that includes a first wireless communications system that has a core network and a second wireless communications system that includes several short range access points using licensed wireless frequencies and a network controller for communicatively coupling a user equipment to the core network. The method determines, by a first access point, to handover the UE to a second access point. The UE has at least one ongoing session with the core network through the first access point. The method sends a relocation required message to the network controller. The relocation required message includes a domain identifier for said message. The method receives a relocation request message from the network controller. The method receives a relocation command message from the network controller for causing the UE to handover from the first access point to the second access point.
